The Sun Hydraulics DNDAXCN72499 (DNDAXCN72499) is a solenoid-operated 4-way, 2-position cartridge valve designed for versatile directional control in hydraulic systems. This direct-acting, balanced spool directional valve does not require a minimum hydraulic pressure to operate, making it suitable for various applications. The valve's solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. It features a wet armature design where the working fluid surrounds the armature, providing efficient heat dissipation from the coil but requiring consideration of fluid type due to potential varnish formation over time. The DNDAXCN72499 model offers several manual override options, with some configurations featuring a detent mechanism intended for temporary actuation. The manual control assembly has an estimated mechanical life expectancy of approximately 7,000 cycles. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended to avoid damage from petroleum-based substances. This valve supports various coil termination and voltage options, enhancing adaptability across different system requirements. The solenoid's magnetic design maximizes efficiency by delivering high spool actuating force per Watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include a floating style construction that minimizes internal binding risks due to excessive installation torque or cavity-cartridge machining variations. The valve accommodates a maximum flow rate of 10 gpm (40 L/min) and operates with a typical response time of 50 ms. It is engineered for a switching frequency of up to 15,000 cycles per hour and is built to handle maximum leakage at specified conditions efficiently. With its robust construction and adaptable configurations, this cartridge valve is ideal for demanding hydraulic applications requiring precise directional control.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
